The correct solution is 
CSubtract 6 from both sides of the equation
        3x + 6 - 6 = 21 - 6
        3x = 15
Then divide both sides by 3       
 
              x = 5
 
        
        
        
5w=30
5w/5=30/5
w=6
Therefore w is equal to 6
        
             
        
        
        
Answer:
54
Step-by-step explanation:
Substitute n into the equation:
-2(3)[5+3-8-3(3)]
-6[-9]
+54
 
        
             
        
        
        
Answer:
second choice!
Step-by-step explanation:
2x-1 > x+2
[subtract x from both sides]
x-1 > 2
[add 1 to each side]
x > 3
- - - - -
our answer, to fit the inequality, should be:
- dot on the positive 3
- open dot on the line
- the right side of the dot should be highlighted
now choose the second graph since it fits all the requirements!
if i'm wrong pls let me know and always double check bc sometimes im dumb yeah <//3
 
        
             
        
        
        
Answer:
None of the graphs of the equations pass through M(−10, 15).
Step-by-step explanation:
We are given the function  .
.
It is given that the point B lies on the graph of the given function.
1. B(2, −3)
That is, x= 2 and y= -3
So, y= kx ⇒ -3 = 2k ⇒ 
Thus, the function is 
2.  i.e.
 i.e.  
 
That is,  and y= -2
 and y= -2
So, y= kx ⇒  ⇒
 ⇒  ⇒
 ⇒ 
Thus, the function is 
From the graph plotted below, we get that,
None of the graphs of the equations pass through M(−10, 15).
